induction annealing brass contact
• An induction heating coil designed and developed specifically for this application.
Process A one turn hairpin coil is used to heat the electrical contact to 1000ºF (538ºC) in 1.5 seconds. The contacts are in strips at 0.75” (19mm) centers and will run continuously at a rate of 50’ (15.24m) per minute.
Results/Benefits Induction heating provides:
• Hands-free heating that involves no operator skill for manufacturing
• Pinpoint accuracy
• Consistent results
